DESCRIPTION
In the update of this month, a simple grid snapping can be enabled for placing control points of polygons and polylines.
It becomes easier to create right-angle edges in polygons/polylines now.
The grid spacing can be modified in Gizmo->Snap->Grid.
The control points for Bezier polygons/polylines are not on the curves when grid snapping is enabled.
Grid snapping for normal moving gizmo may be added in the next update.
The update will be available for prototype users first.
